Application tiled September 10, 1912. Serial No. 219,510.

To all 'whom it may concern Be it known that I, JOHN SoN'rHarMan, acitizen of the United States, and a resident of Lincoln, in the count ofLancaster and State of'Nebraska, have lnvented a new and I'mprovedTelephone-Directory, of whlch the following is a full, clear, and exactde scription.

This invention relates to telephone directories and has reference moreparticularly to a4 evice of this class which comprises a plurality ofcircular members carrylng reference characters and provided with meanswhereby any desired reference is rapidly found.

An object of the invention is to provide an inexpensive and compacttelephone directory, sim le and durable in'its construction, an whic canbe easily attached to a telehone and' will not, interfere with itsaction or add much to its bulk.

Another objectof the invention is to provide a telephone directorycarrying telephone references and addresses of such parties with whommost of the telephone connections are made, and to locate suchreferences when desired with a minimum expenditure of time.

A further object of the invention is to provide a device to whichtelephone references may be easily added or replaced, the addition ofthe reference not requiring any chan e in the structure of the device.

Re erence is to be had to the accompanying drawings forming a part ofthis speciication, in which like characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is a faceelevation of an embodiment of my invention partly broken away to exposeone of the reference disks, the dotted position of the disk showin theposition when looking for a desired tele one number; Fig. 2 is a part ofthe device in section taken on the line 2 2 in Fig. 1; Fig. 3 isanenlarged perspective view of a part of the reference carrier; Fig. 4 lisa perspective view of the roller with the loop member; and Fig.v 5 is aperspective view of the telephone Iprovided with my device.

Before procee ing to a more detailed description of my invention it mustbe understood that the drawings submitted show only a special type of atelephone and' that my device may be attached to any form of a telephoneby a corresponding modification ofthe means of attachment of. my device.The reference carriers may be circular or of any other shape, and,similarly, the casing for said disks.

Referring to the drawings, 10 is a casing preferably cylindrical inshape, having its ends formed by means of circular end walls 11 and 12and its lateral surface 13 only semi-circular; thus an opening is leftin the casing on its lateral surface between the end walls 11 and 12.Loosely fitted in said casino' is a plurality of circular disks 14 provied with an engaging edge ring 15 straddling the ed e of the disk 14, thediameter of. said ring eing a little less than the interior diameter ofthe casing 10. The disk 14 is provided on one of its faces with acircular pieceof paper having the roper references printed or otherwiseprovided on this paper. The paper may b secured to the disk by pastingsame on the disk, or clamping means may be provided on the disk formaintaining the paper on same. The ring 15 is provided wlth a fiange 16projecting above the lateral surface of the casing 10, and is providedwith a letter stamped in said flange, or otherwise secured to same, andindicating the name of the party whose name begins with the sameinitial.

The disks 14 provided with the rings 15 are interposed by means of smallcircular disks 17 so that the rings'15 bear easil with their sidesagainst the face of the disly: 17. Thepurpose of the smaller disks 17 isto prevent interference between any air of consecutive rings 15. Theso-forme a1- ternate series of circular disks 14 and 17 areeccentrically mounted on a pin 18 rigidly fixed in the walls 11 and 12of the casing 10 near its lateral surface and projecting out of thesides. The edges of the disks 14 and 17 are normally at the same levelwith respect to the lateral surface of the casing 10. The disks 14 beingeccentrically mounted near the lateral surface of the casing 10 whenswung on the pin 18 out of the casing will expose the maximum of theirface carrying the referencmhxle the disks 17, being fixed on the pin 18,will not he. displaced. The projecting pin 18 at one of its ends carriesa wire coil spring 19 having one of its ends fixed on the end wall. 11;the other end of t-he said spring 19 forms a loop member 20 about thelateral surface of the casing and resting on the other end of theprojectin pin 18. The part of the loop 20 para-lle to the lateralsurface `of the casing 10 is provided with a rubber roller 21. The loop20 and roller 21, by means of the coil spring 19, are continuouslyforced toward the' lateral surface of the casing 10. rlhe casing 10 isalso rovided with a split ring 22 having two en flanges 23 formed in thesplit and adapted to receive a bolt 24. The ring 22 is also providedwith a projecting portion 25 in line with the lateral surface of thering and riveted or otherwise secured to the wall 12 of the' casing 10.By means of the solit ring 22 the device is placed' on the body ofthetelephone 28 and cla-m ed to same by the medium of the bolt 24 (see igs.1 and 5) The lateral surface of the casing 10 is also provided with ahooked member 2G' adapted to receive the paper 27 to be used formemorandum when necessary.

My device, iis-shown in Fi 5, is placed so as to have the indicating ane16 provided with the letters of thealpha et to face the erson using thetelephone. When a num er is to be called the initial of the name of saidartybeing found on the indicator fiange, yA forcing this--.flangcto `theleft (Fig. 1) the face ofthe disk 14 carryin' thepapcrs with theprintedl narines, telep one,

number and address, is exposed and can be readily seen and the desiredartys name is easily found, as shown in otted lines in Fi 1. By theoutward movement of the -dist 14 the rubber roller 21 is also forcedaway from the lateral surface of the casing 10 and thereby increases thetension of the winding of the coil sprin 19 so that when the fingerholding the in i'cating flange 16 is released the spring 19 forces thedisk 14 to its original position by meiins of the roller 21,` as can beeasily seen from the drawinffs.

It is readily seen that with my device tie expenditure of time requiredto find the numbers of the parties with whom most of the telephoneconnections are made is diminished to a minimum; the reference being`attached to the telephone itself cannotbe mislaid,` and any desiredadditional reference can be easily made either by rinting directly onthe aper fixed to the disk 14 or by pasting or ot erwise securing a newpaper t isk on the disk 14.

Having thus described my invention, what l claim as new and desire tosecure by Letters Patent is :--A
